- Inventory files may simply consist of a list of hostnames but can be much more robust

- It is also possible to define groups of hosts, host or group level variables, and groups of groups withing the inventory

- There are a number of variables that may be used within the inventory to control how ansible connects to and interacts with target hosts

- Commands to call ansible with `ping` module:
    - ```ansible innaghiyev1c.mylabserver.com -m ping -k``` - call ping module on `innaghiyev1c.mylabserver.com` host. Where `-m ping` is ping module
    and `-k` is key for asking password
    - ```ansible all -m ping -k``` - call all defined hosts in your inventory list `/etc/ansible/hosts/`
    - ```ansible -i inv.ini httpd -m ping -k``` - where `-i` - inventory file place, `httpd` hosts group name inside of `inv.ini` file
  
Output:
```
innaghiyev1c.mylabserver.com | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python"
    },
    "changed": false,
    "ping": "pong"
}
```
